A Lehigh University junior was found dead tonight in her off-campus apartment, according to the Northampton County coroner and officials at the South Bethlehem school.

Today marked the return of Lehigh students to campus for the fall semester.

Hanlon MacDonald, 19, of Albany, N.Y., was found by her roommates in her apartment about 6 p.m. in the 500 block of Fillmore Street, Coroner Zachary Lysek said late tonight.

The cause and manner of death are pending an autopsy and toxicology testing, Lysek said.

School officials said in an email to the campus community that the death doesn't appear suspicious.

"The cause of death has yet to be determined, but there is no indication of foul play," Vice Provost for Student Affairs John W. Smeaton said in the email. "The condolences of the university community go out to her family at this very difficult time."

Northampton County District Attorney John Morganelli, who is out of town tonight, said he had spoken with Lysek and it appears the victim died as a result of some underlying illness, but stressed the case is still being investigated.

Lysek declined to speculate about MacDonald's death before an autopsy is performed.
